Honestly, 16-year-old me would be both impressed and disappointed in my current self.
For example, he would be disappointed that I “threw away” a “nice relationship”, unbeknownst to him that the relationship would nearly ruin his life and connections to his friends and family, like he has never experienced before.
But he would be impressed as well - he would see, that his dream of “doing computer stuff” would proliferate, although he would ask himself why I own so much “junk parts”. And he would be impressed that his father finally trusted him for his expertise, regardless of age or relation.
